Soon after his death Perdikkas, to whom in his last moments he had given his signet-ring, was appointed to conduct the government on behalf of the royal family, which was held to consist of Arrhidaios, the king’s half-brother, a man of weak intellect and character, and Queen Roxana, who a few months after her husband’s death gave birth to a son who received the name of Alexander Aigos. The satrapies were then divided among the leading generals. Perdikkas soon began to use his position for the furtherance of his own selfish designs, and having secured the support of Eumenês, attempted to crush his colleagues and assume all power to himself. He marched first into Egypt against Ptolemy, but on the banks of the Nile he was defeated and slain in a mutiny of his own men 321 B.C. Tidings soon afterwards reached the army that Krateros had been defeated and slain in fighting against Eumenês while marching to assist Ptolemy. The office of regent was upon this offered to Ptolemy, who declined its acceptance, as he held that the satrapies should become independent kingdoms. The army then conferred that office, along with the tutelage of the royal family, on Antipater of Macedonia, who had crossed over into Asia to oppose Perdikkas. A new partition of the provinces, which did not differ much from the former, was then made at a place in Upper Syria called Triparadeisos. Under this arrangement Ptolemy held Egypt; Lysimachos, Thrace; Antigonos, Phrygia or Central Asia Minor; Seleukos, Babylon; Antigenes, Sousiana; Peukestas, Persia; Peithôn, son of Krateros, Media; Nearchos, Pamphylia and Lycia; Arrhidaios, Hellespontine Phrygia; Antipater and Polysperchon, Macedonia and Greece. Eumenês still held the satrapy at first assigned to him—that of Kappadokia, Paphlagonia, and Pontos—and was now the leader of those who had been the adherents of Perdikkas. He was supported by Alketas, the brother of Perdikkas, Peukestas, Attalos, Antigenes, and by the influence of Olympias, the mother of Alexander. Besides Perdikkas and Krateros, two other great generals had by this time disappeared from the scene—Meleager, who had been cut off by Perdikkas, and Leonnatos, who had been slain in the Lamian war.
